LUBRICATOR FOR PNEUMATIC ENGINES- Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed September 20,1904- Serial No. 225,279.

To all whom it may concern:

Be it known that I, WILFRED Lnwrs, a

- citizen of the UnitediStates,iandfairesident of simple, durable, and efiicient means for lubricating thereciprocatory piston of such enmes.

of features of construction and combinations of devlces herelnafter described, and moreparticularly pointed out in the appended claims. v

The referred form of the invention is illustrated in the accom 'anying drawing, forming art hereof, in'w ich T e reference 1 marks the barrel, and 2 3 the heads or ends of the cylinder, which are connected by screw-threads or in other suitable manner.

4 marks jaws on the head 3, whereby the vibrator-engine shown may be attached by a bolt and nut 5 to a pattern, pattern sup ort or carrier, or other part which it is desired to vibrate or actuate.

6 represents recesses in the heads 2 3, which are filled with felt or other absorbent 7, and Srepresents assages through the heads 2 3 whereby the lubricant may be introduced.

'9 represents screw-plugs for closing said oilholes 8.

The reference 10 marks metal plates or disks provided with central perforations 11 therein, said disks being seated against the heads 2 3 andbeing held in place by the barrel 1 and the heads 2 3, as shown.

12 is a piston or hammer fitting and moving in the barrel '1 and provided with circumferential grooves 13, which communicate with the ends of the piston 12 through axial and transverse holes 14:, one groove 13 with one end and the other groove with the other end of the piston.

To the ends thereof the invention consists engines employed for p with the 15 is the supplyort, which communicates I with the' interior 0 the barrel 1 through the passagesilo.

17 represents exhaust-ports. e The pressure and exhaust ports 16 and 17 are so located with relation to each other and the grooves 13 that the piston is drivenlback and forth automatically, as usual.

The reference 18 marks a springwhich is set inacavity in one end of the iston 12 and in a recess in the front face of the plate or disk 10. The spring 18 is tensioned to push the piston 12 to the far end of its stroke, whereby it is normally in a given or starting position.

In the operation of the engine the piston is' driven back and forth, automatica and strikes against the disks 10, and the oi or lubricant is forced through the foraminous disks 10 into the cylinder 1 and lubricates the piston automatically while it is in o oration.

he lubricant may be introduced w en there is no air-pressure on in the engine through the holes 8, as will be understood.

The invention may be used in pneumatic oses other than vibrating a pattern in mo d-making. Also it may be used at but one end of the engine, if so desired.

I do notlimit myself to the precise form of the invention shown in the drawing and above described, since details may be varied Without departing from the spirit of my invention.

What is claimed as new is 1. In a pneumatic engine, the combination with the barrel thereof, of an end closure pro-v vided with a recess in line with the opening of said cylinder or barrel and opening toward or inward of said barrel, a lubricant-absorbent in said recess, and a perforated cover for said recess with a free piston in said barrel which strikes said cover.

2. In a neumatic engine, the combination barrel thereof, of an end closure thereon and provided with a recess in line with the opening of said barrel and opening inward of said barrel, a lubricant-absorbent in said recess, and a perforated plate covering said recess and he d in place by the barrel roo refwhihstriks'g&ifist thesz'mid covr.
